Abstract：Objective To compare the efficacy of endoscope-assisted and pure microsurgery on acoustic neuroma.Methods The clinical data of 72 patients with acoustic neuroma admitted to the Neurosurgery Department of The First Affiliated Hospital of Nanjing Medical University from January 2019 to July 2022 were retrospectively analyzed.The patients were divided into an observation group(endoscope-assisted+microsurgery)(28 cases)and a control group(microsurgery)(44 cases)according to different surgical methods.The tumor resection rate,the range of the removal of the posterior lip of the internal auditory canal,the postoperative complication rate,and the facial nerve function(House-Brackmann grade)before and 6 months after operation were compared between the two groups.Results There was no significant difference between the observation group and the control group in total tumor resection rate and postoperative nerve function rate(P＞0.05);The removal range of the posterior lip of the internal auditory canal in the observation group(5.70±0.58 mm)was significantly smaller than that in the control group(6.70±0.58 mm)and the incidence of complications in the observation group(7.14%)was significantly lower than that in the control group(27.3%),and the difference was statistically significant(P＜0.05).Conclusions Endoscope-assisted microsurgery can reduce the abrasion range of the posterior lip of the internal auditory canal,thus reducing the occurrence of complications.
